davit drives 16.5 miles in 10 minutes.
he passes a sign which gives the speed limit as 65 mph.
by how much, in mph, did davit's average speed exceed the speed limit?

34 mph

Step-by-step explanation:

Davit's average speed in miles per minute

= 16.5/10

= 1.65 miles per minute

Davit's average speed in miles per hour

= 1.65 × 60 (Since there are 60 minutes in 1 hour)

= 99 mph

Difference = 99 - 65

= 34 mph

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
